DESCRIPTIONS OF TWO NEW SPECIES 



OF PHYTOPHAGOUS COLEOPTERA FROM THE ISLAND OF NIAS 



BY MARTIN JACOBY 



A small collection of Phytophaga from the island of Nias 

 obtained by Mr. H. Raap has been kindly submitted to me for 

 examination by Dr. Gestro ; amongst these, several new species 

 are contained, but only two of them I am enabled to describe, 

 as the others are only represented by single not always per- 

 fect specimens belonging to obscure and difficult genera. The 

 rest of the species are identical with those which were obtained 

 by Signor Modigliani and of which I gave a list in the Annals 

 of this Museum in 1889. Some others were described by Hen* 

 Weise from the same locality in the Deutsche Ent. Zeitsch. 1892. 



1. Rhyparida Raapi, sp. nov. — Testaceous, eyes large, tho- 

 rax transverse, very finely and rather remotely punctured, 

 elytra with basal depression , strongly and remotely punctate- 

 striate, the punctures finer posteriorly. 



Length 5 mill. 



Head with a few fine punctures at the vertex, the latter 

 much narrowed on account of the large sized eyes, these distinctly 

 notched, clypeus transverse, separated from the face by a few 

 punctures only, its surface also very sparingly punctured , its 

 sides rather raised in shape of a ridge, labrum fulvous, man- 

 dibles black, antennae testaceous, the third joint elongate, slightly 

 longer than the fourth, terminal joints slightly widened ; thorax 

 scarcely twice as broad as long, the sides evenly rounded, the 

 anterior angles produced in shape of a small tooth, the disc 

 remotely but distinctly punctured, scutellum with the apex
